YOu actually paid the interest because he wasted his money all year?
This story sounds like the turtle and teh hare tale perfectly... He wastes the year while you work diligently and plan ahead and at the end of the year, he isnt' prepared and you cross teh finish line...
But he expects you to bail him out like his parents do...
I think it would be healthy to work on finances together, but If your H is that unrelaible I can understand why you would want to save separately...
I think if you had given him access to all the finances thy would likley be gone and you WOULD be accusing him of financial infidelity...
WOrking together on finances is healthy for a marriage, but if your spouse isnt' responsible with fiannces its best to do what you can to motivate him to learn to be responsbile and to protect yoruself as you have done
